MACHINE FOR SPINNING HEMP, 84.0.

SPECIFICATION forming part of Letters Patent No. 402,785, dated May 7, 1889.

Application filed February 20, 1889, Serial No. 300,591- (No model.)

To all whom it may concern:

Be it known that 1, CHARLES H. TRIPP, of Boston, in the county of Suffolk and State of Massachusetts,have invented a new and 'useful Improvement in Machines for Spinning Hemp, &c., of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a safety-guard mechanism for spindles for hemp-spinning machines; and the object of my invention is to prevent the running of the machine unless the spindle is in proper position, and to guard against any negligent arrangement of the spindle and flier, which often causes serious damage to the machines and those operating them. I attain this object by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a spinningmachine with mymechanism therewith. Fig. 2 is an end elevation of the same. Fig. 3 is a side elevation of the safety-guard mechanism with the frame in cross-section. Fig. 4 is an elevation of the latch and connecting-rod and as sociated parts, same being in section. Fig. 5 is a longitudinal section of the latch and frame.

Similar letters refer to similar parts throughout the several views.

A is the frame of the machine, of convenient form to contain the working parts. Bis the capstan-head of the flier; C, the flier-rods; D, the driving-head of the flier; E, the spindle; F, the bobbin; G, the pulley on the fliershaft H; I, the pulley on the driving-shaft-J; K, the belt connecting the pulleys G and I.

L is the shipper passing through the brackets Z and Z and provided with the projection Z and bolt-pin Z Z is the fork of the shipper, which passes around the belt in the usual manner to throw the belt on a loose pulley when required.

M is the shipper-bar, of well-known construction and arrangement, which is operated by a clutch in the manner well known to those skilled in the trade.

N is the shipper-lever fastened on the shipper-bar M by means of a screw-bolt or any suitable mechanical device, and slotted to receive the bolt-pin Z' and thus move the ship per Lwhen the shipper-bar M is turned.

- The construction of all of the above-mom tioned parts is well known to those skilled in the trade.

The lever N is provided with an arm, 0, to which is pivoted by pivot o the screw-plate P.

Q is the journal-box secured to frame A, in which rests the end of the spindle E. The outer end of the box Q is provided with two grooves, q and g in which operate, as hereinafter described, the latch-plate R.

S is the lock-plate, which is pivoted to the box Q by the pivot s, and has an arm, 8 curved at the top, and an arm, .9 pivoted to the connecting-rod T by pivot 5 R is the latch-plate, which is adapted to slide in the grooves q and g of the box Q.

f is the end of the spindle, adapted to be held in the capstan-head of the flier. f is the end of the spindle in the box Q.

T is the connecting-rod, at one end pivoted to arm 8 of the lock-plate S, at the other end threaded, and fitting into the above screwplate P, which is correspondingly threaded to receive it.

e is a hinge-plate pivoted to the box Q, and which is pushed up when the spindle E is pulled out, as shown in Fig. 5, but which may be used or not, as desired.

For the purpose of illustration, a double spinner is shown in the drawings but my invention is applicable to each machine separately. The driving-shaft J may be operated by any suitable system of gearing. If the spinner is stopped to remove the bobbin or fix the spindle when the-hemp breaks, by turning the shipper-bar M with a clutch, the arrangement .of which is automatic in most spinning-ma chines or any suitable mechanical contrivance, the shipper L is moved forward and the fork Z throws the belt on a loose pulley. The lock-plate S is at the same time lowered by means of the lever N moving down the connecting-rod T. Onsliding up the latch plate R the spindle E may be moved out, the latch-plate resting upon it. The end f is then outside the box Q and end f away from the capstan-head B of the flier, as shown in Fig. 1. The curved arm .9 of the lock-plate S rests against the raised latch-plate R, as shown in Fi 2.

ft is obvious that the machine cannot be started up again until the latch-plate R is down, as the arm 8 resting against it, prevents any movement of the lever N, with which it is connected by the rod T, thus preventing any running of the spinner until the spindle is in place, and guarding against damage and breakage, often occurring through neglect to adjust the end f of the spindle E in its bearing. On sliding down the latchplate R the machine may be immediately started up by the shipper-bar operating the le ver and shipper in the usual manner,whi1e at the same time the arm .9 of the lock-plate S is raised and the curved arm .9 moved over the top of the latch-plate R, preventing any upward movement of said plate by the curvature of arm 8 The latch-plate R also prevents any Working out of the spindle when the spinner is in motion. 13y manipulation of the screwplate P and threaded end of rod T accurate adjustment of the movement of lock-plate S by lever N may be obtained.

IIaving described my inventiomwhatl claim, and desire to secure by Letters Patent, is

1. In a safety guard mechanism for spindles for hemp-spinning machines, in combination, the box Q, provided with grooves, the latchplate R, sliding in said grooves, the lock-plate S, pivoted to said box Q, and having a curved arm, 8 and an arm, 5 connecting-rod T, pivoted to the said arm 8 the screw-plate P, pivoted to lever N and adapted to receive the threaded end of said rod T, the lever N, at one end fastened to shipper-bar M, at the other end arranged as described, with the shipper L, shipper-bar M, and shipper L, connected by said lever, as described, all substantially as described, and for the purpose set forth.

2. In a safety-guard mechanism for spindles for hemp-spinning machines, in combination with the frame, a spindle having its outer end bearing in a box on said frame, which box is provided with grooves, a latch-plate sliding in said grooves of said box over the end of said spindle, a lock-plate pivoted to said box and having an arm adapted to rest against the edge of the 1atch-plate When out of the groove, and an arm pivoted to a rod, said rod being connected by a pivot to a shipper-lever, a shipper-lever fastened at one end to a shipper-bar and at the other end slotted to receive the pin of a shipper, and a shipper-bar and shipper connected by said shipper-lever, as aforesaid, all substantially as described, and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 7th day of February, A. D. 1889.

CHARLES 'H. TRIPP.
